      Several other authors of software that accesses the Twitter API have come to that conclusion as well. When #Twidere, my phone app to access Twitter stopped accessing Twitter back in January I pretty much abandoned Twitter. I still check Twitter with its WebUI, less than once a week, but I no longer post or engage […]

      bobjonkman favorited something by steve: I finally had a chance to figure out why my social bridging software was no longer able to talk to Twitter. Indeed, it's because under Twitter's new leadership, python-twitter has been deemed as violating something in their terms of service. It says I can submit a ticket, but they make […]

Invalid HTML considered harmful

Posted by Bob Jonkman on 28th April 2009

Valid HTML is not just useful for browsers. One of the big benefits of having valid HTML is that search engines can properly index your site. If the HTML is invalid, then the search engines may index you incorrectly, or not at all. Google isn’t the only search engine out there, and you want to drive as much traffic to your site as possible.

There appears to be some contention whether valid HTML makes a difference to search engines or not. Some say it doesn’t; or that it depends on the search engine; others have evidence it matters a lot.

Favicon - HTML DogHTML Dog (blue and white posterized picture of a dog's head (boxer?) between two angle brackets, as if it were an HTML element)https://htmldog.com/

Even if you’re not coding by hand, I urge you to have a look at HTML Dog, a set of tutorials on creating valid HTML. When things don’t work as expected you can turn here for examples in XHTML.

Favicon - Kompozerhttp://kompozer-web.de/

If you’re going to be using an editor for your Web pages, pick an editor that creates proper HTML code. Abandon FrontPage. I suggest using KompoZer, which is based on the same rendering engine as Firefox (Gecko).

Favicon - Opera.comhttp://opera.com

You should also be checking your pages in Opera, which is a browser that is even better for standards-compliance than FireFox. The Chief Technology Officer for Opera is the same guy that wrote the Cascading Style Sheets specification, so it has a good pedigree.

If you’re using Firefox then be sure to check your pages with the HTML Validator addon:

Favicon - Skynet.behttp://users.skynet.be/mgueury/mozilla/

And when you think your site is done, check each page with the full-strength validator:

Favicon - W3C HTML Validatorhttp://validator.w3.org/

Favicon - CSS Validation Servicehttp://jigsaw.w3.org/css-validator/
